Checkin out recievers today and came across a Harmon Kardon AVR 510 . This model will not be carried anymore and the new ones are due in soon. They want $1198.00 canadian for this demo . I feel that is way too much. I should wait till the new ones are out like the 520 320 220 120. I am interested in the Harmon Kardons. What do you guys think?
